Some good news to report for once.
Talked it over with an old time mechanic, and he was thinking the coil may have been at fault. He said that a bad coil could be totally fine at idle, but then cut out when it overloads under demand. So I replaced it with the same one from Napa.
Also checked my gas cap and it is not plugged. There was a small section of rubber fuel hose that I had missed before, so I replaced that for good measure.
I did several small loops of about 5 miles total and the car never died under power like it did before. It did however die several times when coming to stop not in gear.... When the engine dropped back down to idle. It started immediately again. I adjusted the idle speed screw to a higher idle and it helped some but didn't solve it completely.
My electric fan is working as it should. The engine stays between 170-175 and the fan is quiet.
The engine still is not running as well as it should. It misses and stumbles a bit, and is inconsistent. Vacuum gauge is at 20, but dips at the same time there is a miss/stumble.
Everything on ignition is new except the plug wires. I don't think my bending the arm on the carb to adjust idle did any good. I think I may have made things worse by doing it. All the pictures I've seen of Super 8's so this carb have it bent/set the way it was. Not sure what to do there.
Didn't get a picture today because we are covered in smoke. But here's a nice one from this last weekend.
